Hello all, I have a few pics of two types of trees i'm trying to id. I think the first is a Silk Tree. First is very similar to albizia julibrissin, if not the same tree. My 400 year old neighbor just calls them mimosas, but isn't sure of their exact name.

Both trees in question. One Singular, the other a multi-branched bane of existence.

Different set, again both trees, in foreground and midground, are same type. foreground tree has been cut some.

What happens when they are continually cut down to ground level. They turn into a giant stump. I cut off last years growth off this thing back in early summer, and have weed-ate all the shoots about 4 times since then. Drilled a few holes in this about a month back and poured boiling water on it a few times.

Same stump. I've been tormenting this stump almost all summer, so it's pretty weak now, but still supporting all those shoots. every one of them would be 3 feet long by this time next year if i left them.

Following are a few pics from random samples of some of the younger ones.

Few shots of the average root structure, these are all the same root.

As far as characteristics, I never noticed until i was taking pics this morning, but all the younger ones are still a vibrant green/healthy color yet all the older ones that produced seed pods this year, have lost their leaves. i figure it has to do with energy to generate the pods taking priority over generating leaves.

And this pic of a albizia julibrissin on wikipedia, while not taking from the ones on my property, is pretty similar to the flower the older ones produce pretty early in the season.

Anyway, I've pretty much beat them into submission over the last 3 years by cutting them down to ground level and eventually digging/pulling them out. some of the really big ones, I've managed to kill by placing brush fires on right on them, but even then it takes a few fires to finish off the ones that are 8-10 y/o. as shoots will sprout right out of the side shoot roots.

2nd trees are these. Luckily their roots are very shallow and 99% can be pulled right out of the ground, roots and all, with no fuss by my stock 2wd Mazda. I've only met one that needed a little extra motivation.
